# CLAUDE.md — OpenShift Expert

Expert agent for explaining OpenShift Container Platform behavior, architecture, and operational patterns. Knowledge is stored in `reasons.db` — a justified belief network with retraction cascades, not a flat knowledge base.

## Mission

Help humans and LLM agents understand OpenShift platform architecture, operator lifecycle, networking, security, virtualization, and edge deployment patterns. Answers should be grounded in the belief network (`reasons.db`), not parametric knowledge. Use `reasons search`, `reasons explain`, and `reasons show` to find and cite beliefs before answering.

## How to Answer Questions

1. `reasons search "relevant terms"` to find beliefs
2. `reasons explain NODE` to trace justification chains
3. Synthesize an answer grounded in the beliefs found
4. Cite node IDs so the questioner can audit the chain

## What This Expert Knows

- Platform model: operator-driven immutable infrastructure, RHCOS, MCO
- Hosted Control Planes (HCP): multi-tenancy, topology variants
- Networking: OVN-Kubernetes, Multus, SR-IOV, IPsec, egress firewalls, network policies
- Virtualization: OpenShift Virtualization (CNV/OCP-Virt), live migration, VM management
- Operators & OLM: Operator Lifecycle Manager, OperatorHub, File-Based Catalogs
- Security: SCCs, RBAC, OAuth, webhook admission, network policies
- Builds & CI/CD: S2I, Shipwright, Jenkins, GitOps, image streams
- Edge: ZTP, TALM, Single Node OpenShift (SNO), vDU workloads
- Observability: monitoring, logging, Network Observability (NetObserv)
- Storage: CSI drivers, dynamic provisioning, OADP backup
- Installation: IPI/UPI, platform-specific (AWS, Nutanix, IBM Cloud, bare metal, Power)
- Node management: MachineConfig, autoscaling, health checks, tuned profiles

## Skills Available

```bash
reasons search QUERY              # Find beliefs by keyword
reasons show NODE                 # Full details + dependents
reasons explain NODE              # Trace justification chain
reasons list                      # All nodes with status
reasons list --premises           # Foundation beliefs
reasons list --has-dependents     # Load-bearing beliefs
reasons export-markdown -o beliefs.md  # Export readable snapshot
